In last week’s Digest, Robert Rapier aptly stated the challenge in front of XTL technologies – companies whose primary focus is gas-to-liquids (GTL), coal-to-liquids (CTL), or biomass-to-liquids (BTL):
“The two major problems with any of the XTL technologies are that capital costs are extremely high, and a long-term, cheap feedstock supply must be secured. Shell’s initial estimate for the [Pearl GTL plant in Qatar] was $5 billion, but by the time the project was completed the costs were estimated to be around $20 billion.”
